The Weight of U.S. Coins

The United States government began minting coins in 1792, according to the U.S. Department of the Treasury. Of the four minting facilities, currently only the mints in Philadelphia and Denver produce coins daily for commercial use. The two facilities combined produce between 65 and 80 million coins a day. The mint creates each coin at a regulation weight for distribution. The values per weight are based on the closing metal prices as of October 1, 2010.

  Composed of plated zinc, the Lincoln cent, or penny, weighs 2.5 grams. Based on intrinsic metal value, a 1909 to 1982 (95 percent copper) penny is worth 2 cents, while a 1982 to 2010 (97.5 percent zinc) penny is worth only .5 cents.
Jefferson Nickel
- The nickel through the years
  
  The nickel is made of cupro-nickel and weighs 5.0 grams. The value of nickel metal increased by 22 cents in 2010, to $10.7879 per pound, causing a 1946 to 2010 nickel to be valued above face price at 5.99 cents.
